44' claims. (c1. 3o`-1z) The present invention relates to a safetyrazorand has for its objecttoprovide a deviceof this nature which is simplein itsconstructiom capable of being easily assembled and disassembled v5with respect to its various parts, inexpensiveito manufacture,l easy tomanipulate, thoroughly-efficient and reliable in use and otherwise welladapted to the purpose for which it is designed,

With the above and numerous other objects in 10 view as will appear asthe description proceeds, the invention consists in certain novelfeatures of construction, and in the combination and arrangement ofparts as will hereinafter be more fully described and claimed.

15 In the drawings:

Figure 1 is a side elevation of a razor embodying the features of myinvention.

Figure 2 is a sectional view taken substantially on the line 2-2 ofFigure 1 but showing 2 the clamp plate closed against the blade on theguard plate,

Figure 3 is a side elevation taken at right angles to that shown inFigure 1.

Figure 4 is a plan View of the blade.

25 Figure 5 is a sectional View taken substantially on the line 5-5 ofFigure 3 looking upwardly.

Figure 6 is a similar View looking downwardly showing the blade removed.

Referring to the drawings in detail it will be 30 seen that the numeral5 denotes an elongated shank enlarged at one end as at 6 and having aninteriorly threaded bore 1 in said enlarged end. An externally threadedmember 8 is engaged in said bore 1 and intermediate'its ends has an 35annular outwardly projecting flange 9 engaging the lower or outer endof-the. enlarged end 6 and the member 8 merges into an externallythreaded portion I for the reception of an internally threaded cap IIadapted to be locked in 40 place by a set screw I2. A tubular member I4is rotatably mounted over the enlarged end 6 and has one end turned into provide a 'flange I5 to engage between the cap II and the flange 9. Asleeve I6 has one end threadedly engaged in the 45 upper end of the tubeI4. A guard plate I8 is received on the upper end of the shank to restagainst'the upper end of the sleeve I6. A clamp plate I9 is engaged onthe shank 5 by a screw 20 for cooperating with the guard plate I8 to 50hold a blade thereon in proper shaving relationship. A bead 2| extendslongitudinally of the guard plate I8 and has overhanging portions 22. Ablade B is provided with a slot 25 extending from adjacent one endthrough the other end 55 thereof and adjacent said other end, onopposite sides of `the slot .25, provided with openings 26. vThe clampplate IS; has pins 21 which are adapt; ed Ato pass through the openings2 6fand similar openings 28Y in;Y the guard platey I8. The blade isslidrfrom one end so `that the edges of the 'slot 5 .25 are disposedunder, the overhanging'edges 22 'of the bead ZI. l Bypturningthe, cap II, the shank `5 ismoved-longitudinally off the sleeve I6 and the casingI4, the casing I4 being threadedly engaged with the sleeve I6, so thatthe clamping 10 plate I9 may be disposed in open position as shown inFigures 1 and 3 or in closed or clamping position as shown in Figure 2as will be quite apparent.

It is thought that the construction, operation, utility and-advantagesof this invention will now be quite apparent to those skilled in thisart without a more detailed description thereof.

The present embodiment of the invention has been described inconsiderable detail merely for the purposes of exemplification since inactual practice it attains the features of advantage enumerated asdesirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and inthe combination and arrangement of parts may be resorted to withoutdeparting from the spirit or scope of the invention as hereinafterclaimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

1. A safety razor of the class described comprising a sleeve, a shankslidable in the sleeve,

a guard plate on the shank resting against one end of the sleeve, aclamp plate fixed to the adjacent end of the shank for cooperation withthe guard plate in holding a blade therebetween, a tube xed to the otherend of the sleeve and disy posed about the shank, the other end of theshank being enlarged and having an internally threaded bore, anexternally threaded member in the bore having an external annular flangeintermediate its ends and also having an externally threaded extension,a cap engaged on the extension, a set screw holding the cap on theextension, and said tube having a terminal internally disposed annularflange between the flange on said member and said cap.

2. A safety razor of the class described comprising a sleeve, a shankslidable in the sleeve, a guard plate on the shank resting against oneend of the sleeve, a clamp plate fixed to the adjacent end of the shankfor cooperation with the guard plate in holding a blade therebetween, atube fixed to the other end of the sleeve and disposed about the shank,the other end of the shank being enlarged and having an internallythreaded bore, an externally threaded member in the bore having anexternal annular flange intermediate its ends and also having anexternally threaded extension, a cap engaged on the extension, a, setscrew holding the cap on the extension, and said tube having a terminalinternally disposed annular flange betweemthe ange onsaidfmember andsaid cap, the clampgplate haviugpim projecting therefrom throughopenings in the guard plate.

3. A safety razor of the class described coin# prising a sleeve, a shankslidable in the sleeve, a guard plate on the shank resting against-,foneend of the sleeve, a clamp plate fixed tojthefadjacent end of the shankfor cooperation with the` guard plate in holding a blade therebet'weenfatube iixed to the other end of the sleeve and;,dis
